Abstract

An antenna network system comprises a server including a transmitter and an antenna, and a client including a receiver and a steerable antenna. There is also included a control path which is independently operable of the antennas for communicating control data between the server and client. The server is responsive to signal quality data communicated via the control path for steering at least one of the server antenna and client antenna in a direction for optimising the signal quality of communications transmitted between them. <IMAGE>
